Product use:

Used as a high boiling point solvent, a plasticizer for rubber and plastics, and a raw material for preparing pesticides and insecticides, and an ethylating agent

Triethyl phosphate is a high-boiling point solvent and plasticizer for rubber and plastics, as well as a catalyst. It is also used as a raw material for the production of pesticides and insecticides, and as an ethylating agent for the production of vinyl ketone. In Japan, 70% of this product is used as a catalyst and about 20% as a solvent.

(1) Catalysts: xylene isomerization catalyst; catalyst for olefin polymerization; catalyst for the manufacture of tetraethyl lead; catalyst for the manufacture of carbodiimide; catalyst for the replacement reaction of trialkylboron with olefins; catalyst for the production of ethylene ketone by high-temperature dehydration of acetic acid; catalyst for the polymerization of styrene and conjugated diene compounds; used in the polymerization process of terephthalic acid and ethylene glycol to prevent fiber discoloration.

(2) Solvent: solvent for nitrocellulose and cellulose acetate; solvent to maintain the life of organic peroxide catalyst; dispersing solvent for ethylene fluoride; peroxide agent and diluent for curing catalyst of polyester resin and epoxy resin.

(3) Stabilizer: Chlorine pesticides and stabilizers; phenolic resin stabilizers; sugar alcohol resin solidifiers.

(4) Synthetic resins: curing agent for xylenol formaldehyde resin; softener for phenolic resin for shell molds; softener for vinyl chloride; plasticizer for vinyl acetate polymer; flame retardant for polyester resin.

(5) Triethyl phosphate (Phosphate) It is a high boiling point solvent, a plasticizer for rubber and plastics, and a raw material for the production of pesticides and insecticides. It is also used as an ethylating agent and for the production of vinyl ketone. In Japan, 70% of this product is used as a catalyst.
